microstructure and deformation tempurature condition of aliabad-e damaq mylonitic granite

Microstructural studies in sanandaj-sirjan metamorphic zone illustrated several deformation phases, which have relationship with many important geodynamical evidences. one of the most importan magmatic metamorphic area in ssz is hamedan area. this area contin several magmatic metamorphic complexes and thr ali abad damagh is a mylonite granitoid complex which located in the south of the hamedan area. the ali abad damagh mylonite granitoid complex from petrographic view included quartz, plagioclase, feldspars, biotite and muscovite. also this study show major preferred orientation along the ~ne-sw with shallow to steep dipping to northwest and the stretching lineation is sub-horizontal. the relationship between porphyroclast and the tuexture as well as the preferred orientation indicates a ductile-brittle deformation and formed a protomylonite.quartz deformed grains reveals blg-sgr dynamic recrystallization and feldspar grains shows weak undulose extinction and blg dynamic recrystallization. the term-barometric study, illustrated aliabad damagh granite, metamorphosed and sheared at ~450-500°c under the upper low-lower medium grade mylonitization.
